AbstractMajority of low-sloped roofs are constructed as conventional membrane roofing assemblies (membrane above insulation). Currently, four types of conventional assemblies are typically in use: 1. Mechanically attached assembly, 2. Loose-laid ballasted assembly, 3. Fully- bonded assembly (insulation fastened and membrane adhered), and 4. Adhesive applied assembly (all components fully adhered). Approximately one fourth of North American low slope/commercial buildings are roofed with mechanically attached assemblies (NRCA 2004) and their popularity continues to grow. The present paper differentiates the air intrusion and air leakage performance of the mechanically attached assembly.
